Ticket #1546 (closed enhancement: wontfix)
option to erase expandable disks
|Reported by:||hramrach||Owned by:|
The expandable disks are nice but there is no way to shrink the disk once it is expanded.
Deleting and recreating the disk image is quite annoying as it must be unregistered and re-registered with the VM.
There are two possibilities:
- erase the disk completely - possibly an option in the config of the VM or the disk image manager - this would be helpful for test machines
- discard zero sectors - this could be done as they are written - could be used to save space by erasing free space inside the guest OS
